Answer:
zeros: x = 5, or (5, 0)
domain: x ≥ -4
Step-by-step explanation:
The zeros are the values of x where the graph crosses the x-axis. The graph crosses at x=5, so that is the zero.
___
The domain is the set of x-values for which the function is defined. There is no graph for x < -4, so the graph is only defined for x ≥ -4. The domain is x ≥ -4.
_____
The graph has the appearance of the graph of ...
$6.93 is the answer for your question
Answer:
x = -5 ±4sqrt(3)
Step-by-step explanation:
(x + 5)^2 = 48
Take the square root of each side
sqrt((x + 5)^2) = ±sqrt(48)
x+5 = ±sqrt(16*3)
x+5 = ±4sqrt(3)
Subtract 5 from each side
x = -5 ±4sqrt(3)
